Deposits, prospects, and permissive tracts for porphyry and sediment-hosted copper resources worldwide, with estimates of undiscovered copper resources.
| Tract name | Deposit type | Geology |
|---|
| Solonker | porphyry copper | Paleozoic island- and continental arcs formed by Paleo-Asian ocean subduction beneath the North China craton, and Permo-Triassic rocks formed by collision of the North China and Tarim cratons with Eurasia |
| Gobi-Amur | porphyry copper | Cambrian through Early Devonian igneous rocks that consist mostly of continental-margin arc rocks with some island-arc rocks at the eastern end; mostly covered by the Late Paleozoic Kazakh-Mongol Arc |
| Oyu Tolgoi | porphyry copper | A varied assemblage of Devonian through Triassic igneous rocks that include the Devonian Kazakh-Mongol continental-margin arc, as well as younger rocks related to the Indosinian orogeny (collision of China with Asia) |
